In the Shower
As we mentioned, Apple Watches are water-resistant and even swim proof. Normally, that would mean that they’d be a-okay to take into the shower with you (especially since Apple CEO Tim Cook is said to shower with his own Apple Watch). Unfortunately, that isn’t the case.
The problem here isn’t the water. Instead, it’s the soap. Apple’s documentation notes that contact with soaps, perfumes, cleaning products or chemicals can damage an Apple Watch’s ingress protections. So, over time, you’ll slowly be making your Apple Watch less water-resistant. It’s best to just avoid it.
